The central domain registry
The main database of domain names, their holders and other data. Central Registry is responsible for the administration of specific TLD. Example is the company CZ.NIC for Czech national domain .CZ.
Domain names are unique names of computers and servers on the Internet, under which hides their numerical value (IP address), through which computers communicate. The domain is better to remember for humans than the numeric value. Domain can have multiple levels, which are separated by periods, such as third-level domain kb.wedos.com.
Informations are in a separate article http://kb.wedos.com/en/dns/teorie.html.
Technology using the an electronic signature to authenticate the origin of data in DNS records. This avoids an attacker to substitute false DNS records and direct the domain to a fraudulent website. For further information http://cs.wikipedia.org/wiki/DNSSEC.
ICANN (Internet Corporation for Assigned Names and Numbers) is a nonprofit organization that is responsible for the DNS namespace, the distribution of large blocks of IP addresses, autonomous system numbers, management, etc. Transmits competence to manage each TLD to other entities (registrars).
Some domains may contain National Language characters (eg accents, Cyrillic, Greek and others). These domains are applies the title IDN (Internationalized Domain Names).
Individual or legal person who is the holder of the domain.
Re-registration of a domain(transfer)
The process by which it is possible to transfer a domain between registrars. This process may be different for different types of TLD.
A domain registrar is empowered to manage their domains in the central register. Allows to register and manage damains for their end-users(domain owners). One of the registrars is also our company WEDOS Internet a.s.
Set of nameservers (NSSET)
At least 2 nameservers (with the technical contact who is authorized to manipulate with nameservers). By using these name servers for the domain is specified which DNS servers have to return domain DNS records.
Top Level Domain – Domain listed at the end of the domain name. Eg. Czech National CZ domain is in name wedos.cz. TLD can be divided into several groups according to their importance. Eg. ccTLD (Country Code Top Level Domain), which are the national domain, or gTLD (generic TLD),which are not associated with a particular state, but with a certain relevance (com, net, org, info, biz and others).
